As part of a new series of infographics we have created a global map of social web involvement. We wanted to provide a clear visualisation of the way in which the world adopts social technologies differently. The map visualises the number of active bloggers, social networkers, video sharers, photo uploaders and microbloggers. The length of the curve represents the penetration and the size represents the universe size. We have also included the actual numbers so you can use and apply the universe estimates.
